We show what's inside of us, good people will show you respect and rude people will show their rudeness, no matter who you are, it's not something about you, it's about them, their insecurities, but when you're mistreated and you have no choice but to deal with them! you'll have to learn how to do it, below are some simple tips to help you dealing with rudeness:
1- Keep yourself busy:
Just do what you love until you have no time left for those rude people.
2- Take full responsibility of yourself:
Never wait for anyone to give you any kind of help, you don't need anyone! keep this in your mind, so whatever they're going to do it shouldn't stress you out!
3- Don't expect anything from anyone:
No one owes you anything, not even a good treatment! being kind to people doesn't mean that they'll be kind to you back, it's like expecting a lion not to eat you just because you won't eat him
4- Don't undergrad your self-worth:
Others opinion doesn't define who you are rather it defines who they are, it shows their limitations and insecurities, what other are thinking of you doesn't matter, but how you see yourself is all that matters, they'll keep judging you no matter what you're going to do, let it go, it's not about you, you're good enough! it's about them, about their bad character
5- Let your actions defend you:
Don't react to their rudeness, rather work hard and let your success shut them down, no matter how long it's going to take, keep faith!
6- Avoid negativity:
Don't settle for drama, even if you had a hard day, keep looking for the positive in it, be optimistic about everything, where you are right now doesn't matter, what does is what you're learning.
